swift - 阿拉莫菲尔 4 请求开放天气

Question

正在处理我的第一个 Alamofire 请求和更新到 Alamofire 4 的代码。无法正确更新此 Alamofire.request .responseJSON。我正在查看迁移 documentation : 但不够聪明。有什么建议吗？

    let APIKey = "myAPIkey"

func retrieveCurrentWeatherAtLat(lat: CLLocationDegrees, lon: CLLocationDegrees,
                                 block: (_ weatherCondition: WeatherCondition) -> Void) {
    let url = "http://api.openweathermap.org/data/2.5/weather?APPID=\(APIKey)"
    let params = ["lat": lat, "lon": lon]

    //  Send the request
    Alamofire.request(url, method: .get, parameters: params)
        .responseJSON { request, response, result in
            switch result {
            case .Success(let json):
                let json = JSON(json)
                block(weatherCondition: self.createWeatherConditionFronJson(json))
            case .Failure(_, let error):
                print("Error: \(error)")
            }
    }
}

也许可以帮到你

    Alamofire.request(url, method: .get, parameters: params, encoding: JSONEncoding.default).responseJSON { (response) in

        switch response.result {
       case .Success(let json):
            let json = JSON(json)
            block(weatherCondition: self.createWeatherConditionFronJson(json))
        case .Failure(_, let error):
            print("Error: \(error)")
        }
    }
